Subject [jira] [Updated] (HIVE-24068) Add re-execution plugin for handling DAG submission failures
Date Mon, 24 Aug 2020 23:11:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-24068?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prasanth Jayachandran updated HIVE-24068:
-----------------------------------------
    Description: DAG submission failure can also happen in environments where AM container
died causing DNS issues. DAG submissions are safe to retry as the DAG hasn't started execution
yet. There are retries at getSession and submitDAG level individually but some submitDAG failure
has to retry getSession as well as AM could be unreachable, this can be handled in re-execution
plugin.  (was: ReExecutionOverlayPlugin handles cases where there is a vertex failure. DAG
submission failure can also happen in environments where AM container died causing DNS issues.
DAG submissions are safe to retry as the DAG hasn't started execution yet.)
